Wiring the 2JZ into the MA70 chassis

Wiring the 2JZ into the MA70 chassis

This is for swapping a 1st gen Aristo 2JZ-GTE into a pre89 MKIII

How to read: The first part deals with the connectors that are present and their associated pinouts. So you know what they do and can decide if you want to keep them. For example pin 6 thru 8 on Connector ‘C’ deals with the traction control and can be deleted.

The second section titled ‘Connections’ deals with the the hybrid connections that need to be made between the 2JZ harness and the MKIII harness. Three connectors from the 7M main engine harness are required to be spliced in to the 2JZ harness.

Connector ‘B’ is located at the R154 transmission and is used for the reverse light switch,
and is transplanted for this swap.

Fuel Pump Relay
To activate the relay the 7M TCCS normally grounds pin 6 of connector B1 when the ECU see an RPM signal. This is a safety feature so the fuel pump will stop if the engine stops, if something like an accident were to happen. The 2JZ ECU does not do this and has a separate computer to accomplish this task. At the moment I’m not sure how to swap that computer over. So unfortunately the simplest solution is to physically ground the wire from B1 pin 6. This allows the fuel pump relay to kick on whenever the ignition switch is turned on. However this disables the rpm triggered safety feature. Hopefully I’ll come up with a better solution in the near future.

E9 Connector
Due to the limited pins that have to be messed with on this connector I decided to leave the pin out off the main pin out. Simply reference the pin numbers from above.
